Overview of Test Mode
The test mode has been build in the microprocessor in order to adjust and confirm the
performance of transceiver.
The purpose is to adjust transceiver simply and to confirm the performance of
transceiver smoothly.
(a) Expansion channels “EXP01 - EXP07” will be set as follows:

(B) In CH70, ever time you are in transmit mode, (every time you press PTT), the
following test tone can be outputted:
1st transmission:
Synthetic tone of 1300 Hz and 2100 Hz
2nd transmission:
1300 Hz
3rd transmission:
2100 Hz
4th transmission:
No Modulation
5th transmission:
Return to 1st transmission
(C) Scan the channels between WX10 and EXP04 in the SCAN mode.
Adjustment of PLL Frequency
Adjust the frequency in the transmit mode and local frequency in the receive mode.
-- Adjustment --
Setup the test equipment as shown below.
Set the channel to
CH16
. With the
PTT
switch pressed, adjust
TC1001
so that RF
frequency is 156.80000 MHz ± 100 Hz.
Adjustment of VCO
Adjust the frequency in the receive mode.
-- Adjustment --
Setup the test equipment as shown below.
Connect the DC voltmeter to the test point (
TP1009
).
Set the channel to
CH16
. With the
PTT
switch pressed, adjust
TC1002
so that DC
voltage is 1.5 V ± 0.1 V.
